This publication reviews the growth stages of grapes. For each growth stage (or group of growth stages), the document lists the more effective pesticides used to control insects and disease, their rates, and application timing for Oregon grape growers. It also covers the effectiveness of various fungicides for control of grape diseases; strategies for controlling powdery mildew, botrytis bunch rot, and spider mites; methods of controlling vertebrate pests and vegetation in vineyards; and resources for organic growers. Updated in 2011.
